This is a Bobcat Arms BW94 I bought years ago. I swapped out the Lower with a Cohaire ABi semi Pack. I installed a 4 position Clipped and pinned housing and HK AMbi selectors. A MFI rail and Aimpoint Micro t-1. Surefire rail with Magpul rail covers. A CAA "k" foregrip And a Surefire scout. Collapsible F stock from Adam Webber at HKParts.net | For all your HK Parts and Accessory needs - HKPARTS.NET. Along with a 200 dollar tax stamp for the form 1 (short barreled rifle). I love her! This is the most perfect set up I could think of. It feels light and the stock has no play. It was a fun build and a blast to shoot!.................................Whatcha think?
